SORA - Map for intrinsic ground risk

European unmanned aircraft regulation (EU) 2019/947 Article 11 requires a SORA (Specific Operational Risk Assessment) to be performed for flights which fit into the Specific category of UAS. One part of this risk assessment is to assess the risk to overflown uninvolved people and this map is tailored for the use in this risk assessment methodology. The map is an estimate of the average distribution of population density based on the Global Human Settlement Layer (GHSL) dataset by European Commission, Inhabitants (STATPOP) and Employment (STATENT) statistics from the Federal Statistical Office (FSO). The data should be used as a guideline, meaning that discrepancies can be argued accordingly by the applicant in the SORA risk assessment. For cross-border harmonization the European data is used as a baseline which is supplemented with FSO statistics where there are gaps of missing data. Therefor this includes also estimates for areas used for commercial and industrial purposes. The extent of the map is anywhere the Federal Office of Civil Aviation has authority to grant UAS authorizations which is within Switzerland and Liechtenstein. Further, the data extends 5 km beyond the Swiss border into the surrounding countries to allow a proper fly-away risk assesment of flights very close to the borders.
